Procedure

4 mL of 4 N HCl in 1,4-dioxane was added to a solution of 1-(tert-butoxycarbonyl)piperidin-4-yl 7-[2-amino-6-(4-methylpiperazin-1-yl)pyrimidin-4-yl]-3,4-dihydroisoquinoline-2(1H)-carboxylate (0.10 g, 0.18 mmol) in methanol (1.0 mL). The reaction mixture was stirred at r.t. for 2 h. The volatiles were removed under reduced pressure to afford the product as an HCl salt. Analytic LCMS (M+H)+: m/z=452.2.

Workup

  1. customThe volatiles were removed under reduced pressure
